This invention relates to new and useful improvements in pouring attachments for containers and the primary object of the present invention is to provide a hollow body member adapted to yieldingly embrace a container and including a pouring spout having a pointed end that will be forced into a container as the container is inserted into the body member.

Another important object of the present invention is to provide a pouring attachment for containers including a resilient corrugated body member open at its bottom to receive a container and embodying novel and improved means for ejecting a container from the body member after the container has been emptied.

4 Claims. (Cl. 22288) A further important object of the present invention is to provide a pouring attachment of the aforementioned character including a nozzle construction that is quickly and readily removed from the attachment to permit the same to be quickly and readily cleaned and retained in a sanitary state. i

A still further aim of the present invention is to provide a pouring attachment for containers that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the present invention;

sleeve 12 and an end wall l integrally formed with the sleeve at one end. The side walls of the body member are relatively thin and the same are fluted to provide the corrugated sleeve l2. The body member is constructed of any suitable resilient material so that the sleeve [2 may eX- pand slightly to accommodate and yieldingly grip a container l6 that is inserted into the open end of the body member and thereby eliminate the necessity of having to employ spring arms or catches in order to hold the container within the body member.

An annular support or ring I8 is integrally formed with the end wall M and projects inwardly of the inner surface of the sleeve l2. The ring I8 is provided with an internally threaded opening 20 that receivably engages the threaded end 22 of a tubular puncturing element 24 having a pointed or sharpened lower end 2E that will extend into one end wall of the container l6 as the sleeve I2 is forced downwardly over the container IS. The tubular puncturing element 24 also includes an air port or opening 28 that is spaced beneath the lower surface of the ring 58.

Means is provided for ejecting the container I6 from the open end of the body member or attachment lfl after the container has been emptied. This means comprises a plunger 30 that is slidably received in a central aperture 32 in the end wall or supporting wall Hi. The ends of the plunger 30 are suitably secured to pressure plates 34 and 36 constituting a finger grip and container contacting element respectively.

A coil spring 38 embraces the plunger 39 and is biased between the inner surface of the end wall [4 and plate 36 to urge the plunger downwardly when the container is removed from the body member IE], but the spring 38 is not sufficient to prevent or restrict, to any appreciable extent, the insertion of the container IS in the body member [0.

Means is associated with the body member ii) whereby a fluid in the container Iii may be poured therefrom. This means comprises a substantially L-shaped tubular pouring spout or nozzle 38 having first and second leg portions 40 and 42.

A radial slot 44 extends through the sleeve 12 and the ring 18 andreceives the leg portion 40 of the spout 38. An internally threaded recess 46 is provided in the undersurface of the ring 18 to communicate with the slot 44 and loosely receives the leg portion 42 of the nozzle 38.

An externally threaded ring 48 received on the leg portion 42 of the spout 38 receivably engages the recess 46 and retains the spout 38 detachably secured to the body member I6.

A gasket or sealing ring 59 secured to the nut or ring 40 bears against the undersurface of the ring 18 and will also bear against one end of the container l6 when the pointed or sharpened lower extremity 52 of the leg portion 42 is forced into the end wall of the container 16.

The slot or opening 44 is disposed in a diametrically opposite side of the body member than the tubular puncturing element 24, and the leg portion 49 of the spout 38 bears against the outer and undersurface 54 of the end wall l4 to strengthen the spout construction and to shield the spout construction. Also, the slot 44 is disposed between a pair of the ribs or flutes of the sleeve 12 to further shield the spout or leg portion 46'.

Attention is now directed to Figure 8, wherein there is disclosed the present invention in slightly modified form. In this embodiment, the numeral 58 represents a cylindrical body member or sleeve having a concavo-convex end wall 58.

A spring arm 59 mounted in the sleeve 56 will yieldingly retain a container within the sleeve.

The end wall 58 is provided with a central aperture 6811 that slidably receives a plunger 60b having end plates 62 and 64 secured thereto. The plunger 60b is employed for ejecting a container from the cylindrical body 56.

A tubular puncturing element 59 depends from the undersurface of the end wall 58 and includes 4 opening therein adjacent said end wall, said end wall having a threaded recess in its inner face communicating with said opening, a substantially L-shaped tubular spout having first and second portions, the first portion of said spout being received in said opening, the second portion of said spout being received in said recess, and an externally threaded ring on the second portion of said spout and threaded in said recess for detachably securing said spout to said end wall and said sleeve.

2. The combination of claim 1 wherein said sleeve is corrugated to include a plurality of cira pointed or sharpened end 88 in an opening 10 slightly above the fiat flange or outer circumference 12 of the wall 58.

A tubular spout or nozzle 14 extends through an opening it provided in the wall 58 and includes a sharpened or pointed lower end 18 and M a concavo-convex head portion or lip 80. A sealing ring or gasket 82 embraces the spout 74 and bears against the undersurface of the wall 58.

A closure member 84 is pivoted, as at 86, to a pair of cars 88 rising from the wall 58 and is urged by its own Weight to a position for closing the concavo-convex head portion 84.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the de- A more detailed description is accordingly cumferentially spaced ribs, said opening being located between an adjacent pair of ribs, said end wall including an overhang between said adjacent pair of ribs,the under surface of said overhang being tangent to the upper edge of the opening, and said first portion of said spout contacting the .under surface of saidoverhang.

3. The combination of claim 1 and a sealing gasket about the second portion of said spout and bearing against the under surface of said ring for engaging the upper wall of a container received in said sleeve.

4. A pouring attachment for containers comprising a corrugated sleeve of resilient material adapted to yieldingly embrace a container, a wall at one end of said sleeve, said sleeve having a radial opening therein, a recess in said wall communicating with said radial opening, a substantially L-shaped tubular spout having first and second portions, the first portion of said spout being received in said radial opening, the second portion of said spout being received in said recess, means for retaining the spout relative to the sleeve and the wall, means carried by the wall for puncturing an air vent in a container disposed in the sleeve, the second portion of said spout having a pointed lower end for extending through one wall of a container within the sleeve, and means for ejecting a container from the sleeve, said means for retaining the spout relative to the sleeve and the wall including an externally threaded ring received on the second portion of said spout, said recess in said wall being threaded to receivably engage the ring.
